Abstract (en)
[origin: EP0829958A2] A surface acoustic wave apparatus includes first and second series-coupled resonator filters on a surface-wave board. In each series-coupled resonator filter, the ground electrodes of IDTs disposed at both sides of the center IDT and adjacent to reflectors are connected to different ground electrodes formed on the same layer in the package, with at least two bonding wires.
